Casting a disappearing spell on Paterson's curse

摘要

Paterson's curse, (Echium plantaginuem), sometimes known as Salvation Jane, is an extremely widespread annual weed, covering 30 million hectares throughout south eastern Australia. The annual cost to livestock producers in eastern Australia is well inexcess of 125 million dollar with the weed able to reduce stock carrying capacity by up to 30 per cent. A New South Wales producer, with a desire to return his property to its pre-European state, including freeing it of Paterson's Curse, has successfully used perennial pastures to combat this virulent weed.
